The LG Fresh Air Intake Unit (FAU) is the alternative solution for ventilation which supplies the fresh outdoor air to indoors as well as
being able to cool and heat the inside air simultaneously. It means the indoor space can have positive air pressure consistently which
can block cold, hot or contaminated air from outdoor.
Using the cooling and heating can
save cost by blowing the natural
outdoor air inside when the
season changes.
